As part of the STRAD project for treatments of the radioactive liquid waste, decomposition technology of ammonium ion is developed to preventing formation of ammonium nitrate. In this research, as pretreatment of decomposition of ammonium ion, separation of ammonium ion by zeolite type adsorbent was investigated. And by using simulated solution, separation of ammonium ion was performed.
